SAFETY ATTACHMENT FOR WASHING MACHINES.

Application mea August 15, 1925. Y serial No. 50,423.

r1`his invention relates to washing may chines and has particularreference vto a safety attachment therefor.

The principal object of the present invention is to providean improved attachment for a power washing machine, means for rendering the machine inoperative eX- cept when the doors of the outer casing are closed. v

plates an improved safety attachment for washing machines, which includes means for locking the outer casing doors in a closed condition, which means is operatively connected with the driving mechanism of the machine so that when the locking means is released the driving mechanism is renderedy inactive.

The invention furthermore comprehends a'washing machiney door-locking device having operative connection with the, inner cylinder-driving mechanism for simultaneously rendering said mechanism 'inactive when the locking means is released and for rendering the driving mechanismv active when the lock mechanism is in locking relation to the door.

The invention still further comprehends a safety attachment ofl the character set forth, which is comparatively simple in its construction and mode of operation, which is inexpensive to manufacture and install, and which is thoroughly reliable and highly efficient in its purpose.v Y

With the above recited and other objects in view, reference is had tothe following specification and accompanying drawings in which there is exhibited one example or em'- bodiment of the invention which is in no way intended as a limitation upon the scope of the appended claimsas it is to be clearly understood that variations and modifications which properly fall within the scope of said claims may be resorted to when found eX- r pedient.

Referring to the drawings by characters of reference, 10 designates the substantially cylindrical outer casing or housing of the machine, within which the drums or barrels 11 containing the articles to be'laundered' are rotated alternately in opposite directions Vin the usual manner. The drums or barrels ll-have hinged sections 12 which when opened afford a doorway for inserting' or removing the articles to be washed. The outer casing or housing 10 is likewise provided withan opening'o'r doorway 13 which is'closed by means of a sliding door or closure 14 mounted in guideways 15. The doors or closures 14 are provided with window openings 16 Vclosed by closures 17, by means of which the operator may observe the position ofthe inner barrels' or drums when-*stopping the machine, soy that the am hinged sections will register or coincide with the opening or doorway of the outer casing or housing. l Y v The inner drums or barrels 1 1 are secured to an axiallyextending shaft 18 having secured to its opposite externally disposed extremities, gears 19 with which gears 2O of a reducing train'mesh, which gears 20 in turn mesh with pinions 21. The pinions 21 are secured to the opposite ends of a shaft 22 upon which a pulley 23 is'lreyed. Loosely mounted on the. shaft 22 on opposite sides of the tight pulley 23, are loose pulleys 24 and 25, each respectively driven by 'belts 26 and 27 from a common drive pulley (not shown) on a power shaft.

From this arrangement it will be noted that movement of the lever 52 from the position shown in Fig. 2 to the position shown in Fig. 3, effects a pull on the connecting rodv 69, which in turn effects a pull on the branch chain section 71 which are trained around the supporting arms 74 whereby to draw the slide rod and carriage d6-to a central neutral posit-ion where .the belt-shifting loops 37 and 38 dispose the -belts whollyupon the loose pulleys 24 land 25.

From the foregoing it will be'seen that a safety device has been devised yin which starting of the Vmachine is positively prevented except when the doors or closures 14 are in a closed relation tothe doorway or opening 13, so .asy to allow the bolts 40 to be projected'through the keeper'openings 45. On the other hand, openingv of the doors 14 is prevented until the machinedriving mechanism has been shifted to a neutral position, by the release Vor retraction of the bolts 40 from the keeperopenings 45. Damage to the machine is hence prevented due to the fact that closure of the doorway 14 cannot be effected unless the inner hinged sections 12 are closed with respect to the drums or barrels 11.

What is claimed is: f,

1. In a washing machine including a stationary casing having a doorway, a closure therefor, a drum mounted in the casing for rotation, a reverse driving mechanism for the drum including a drive shaft operatively connected with the drum, a tight pulley secured to said drive shaft, apair of loose pulleys mounted on the drive shaft at opposite sides of the tight pulley, oppositely driven belts respectively engaging the loose pulleys, slidable belt-shifting means for shifting the belts from the loosepulleys into engagement withY the tight pulley to drive the shaft in opposite directions, a rock arm driven by kone of the loose pulleys, a coupling device for connecting and disconnecting the rock arm Vwith the belt-shifting means for actuating the same, a Ysafety attachment for said machine, comprising an apertured portion in the casing closure, constituting a keeper, a locking bolt mounted on the casing, means for normally effecting the retraction and disengagement ofthe bolt from the keeper, and a common manipulating lever movable in one direction for simultaneously engaging the bolt with the keeper for locking-the closure in closed relation to the doorway and for throwing the coupling device in engagement with the rock arm for rendering the driving mechanism active.

2. In awashing machine including a sta-- tionary casing having a doorway, a closure therefor, a drum mounted in thecasing for rotation, a reverse driving mechanism vfor the drum including a drive shaft operatively connected lwith the drum, a tight pulley secured to said drive shaft, a pair of loose pulleysmounted on the drive shaft at opposite sides of the tightv pulley, oppositely driven belts respectively engaging the loose pulleys, slidable belt-shifting means for shiftingk t-he belts from the loose pulleys into engagement with'the tight pulley to drive the shaft in opposite directions, a rock arm driven by one of the loose pulleys, a coupling device for connecting and disconnect- 3 ing the rock arm with the belt-shifting means for actuating the same, a safety attachment for said machine comprising an.v

- apertured-portion in the casing closure, conthe retraction and disengagement of the bolt from the keeper, and a common manipulating lever movable in one direction for simultaneously engaging the bolt with the keeper` for locking the closure in closed relation to the doorway and for throwing the coupling device in engagement with the rock arm for rendering the driving mechanism active, said lever when moved in the opposite direction permitting the disengagement of the bolt from the keeper and the unlocking of the door and simultaneously disengaging the coupling device to render the driving mechanism inactive except when the closure is in fully closed position.

3. The combination with a washing machine of the character set forth, of a safety attachment therefor comprising a keeper on the casing closure of the machine, a. normally retracted locking bolt, a common manipulating lever movable in one direction for Simultaneously engaging the bolt with the keeper to lock the closure in closed position and for throwing a coupling device into engagement with a rock arm for rendering thc driving mechanism on the machine active, said lever when moved in thev opposite direction permitting of the retraction and disengagement of the keeper and simultaneously disengaging the coupling device to render the driving mechanism inactive, and means of connection between said manipulating lever and the slidable belt-shifting means for moving said means to a neutral position simultaneously with the manipulation of the lever to uncouple the coupling device and unlock the closure.
